CONCRETE RAILWAY-TIE.

Specification of Letters Patent.

Patented Feb. 10, 1914.

Application led October 21, 1913. v Serial No. 796,454.

T o all whom, it may concern:

Be -it known that I, ROBERT T. BAGBY, a citizen of the United States, and a resident of Whitney, in the county of'Stanly and State of North Carolina, have invented a new and Im roved Concrete Railway-Tie, of which the olloyving is a full, clear, and exact description.

My invention relates to concrete reinforcing railway ties; and the object thereof is` to provide a st ong, inexpensive and stable tie which has arge bearing areas in the road ballast/for each ofthe rails, and the,

` described hereinafter and fully set forth in p the claims.

' Reference is to be had to the accompanying 'drawings forming a part of this specification, in which like characters indlcate corresponding parts in all the views and in which:

Figure 1 is an embodiment of my invention as seen on lines lll, Fig. 2; Fig. 2 is a longitudinal section on line 2 2, Fig. 1; Fig. 3 is a section on line 3-3, Fig. 1; Fig. 4 is a section on line 4-4, Fig. 1; Fig. 5 is a section n line 5-5, Fig. 1; Fig. `6 is a perspective view, partly in section, of the capV going between the' cushion and the rail;

and Fig. 7 is a perspective view of a clasp' for retaining the spike in the tie.

Referring to the drawings, the tie is formedof a plurality of longitudinal reinforcing members 8, 9 and 9', the member 8 being centrally disposed in the tie and extending at the bottom thereof through the entire length of the tie, with each of its extremities shaped int''a hook 1() and ositioned adjacent the top and the ends o the tie. The reinforcing members 9 and 9l extend parallel to each other adjacent the top of the tie, with their ends 11 and 11 bent so as to follow the end ofthe tie and then mrned up toward the top of the tie, as

shown in Fig`..2. The ends 11 and 11 of the reinforcing members 9 and 9 do not extend to the center of the tie but stop a certain distance from the center, as shown in Figs. 1 and 2, the -reinforcing members 9 and 9 having the central portions 12 and 12' of the same bent in so as to approach each other. These bends 12 and 12 of the portions 9 and 9 make the members farther apart at each end than in the middle.

The members 9 and 9 at each side of their bends 12 and 12 are reinforced by transverse memfbers 13 passing under the members 9 and 9 but above the ends 11 and 11 of the said members. The said members 13 have their ends 13 bent so as to overlap the members 9 and 9 at the top (see member 13 in dotted line in Fig. 4). Thus the members 9 and 9 at each side of the bends 12 and 12 are further reinforced by these transverse members 13,'as can be seen from Figs. 1 and 4. The two central members 13 on each side of the members 9 and 9 are spaced farther from each other than the other members are, so as to permit the formation of a recess 14 when the concrete is molded about the reinforcing members 8, 9, 9 and 13. The molding gives to the tie the shape as shown in Figs. 1, 2 and 3, so that twoindependent sections 15, preferably rectangular in shape, are formed by the reinforcements 9, 9 .and 13 interconnected and reinforced by a web 16 integral therewith and formed by the reinforcing members 8, 11 and 11', bends 12 and 12 of the members 9 and 9.

The recess 14 formed in each section ,15 is substantially in the center thereof and is adapted to receive a Wooden block or cushion 17 which is secured thereinto by means lof a mixture of tar and cement 18 So as to prevent the decay of the`cushion in the tie. The end of the cushion projecting out of the recess isprovided with a metallic cap 19 adapted to receive the base `flange of the rail 20. The clasps 21 for retaining the Spikes are placed in the recess 14 of the tie simultaneously with the placement of the cushion 17 (see Fig. 2). A hooked shaped end 22 is positioned in the bottom of the recess, while a lateral lbent .end 23 forms a support for the clasps on the surface of the section 15. When a spike 24 is forced between the clasps 21 and the cushion, the end of the spike engages into the hook-shaped end 22 of the clasp and forces the end of the hook into the cushion (see Fig. 2), whereby the spike is clamped in position and thereby the rail secured to the tie. Y

As described each of the sections 15 formed of the reinforcing members 9, 9 and 13 has a cushion 17, substantially in the center, on which the tie rests; therefore, each of the ties is provided with two independent sections the center of bearing of which is in alinement with the axis of the rail and thereby two distinct load-carrying sections are formed by the said sections 15. These two sections7 as described, are integrally connected and reinforced by means of the portion 1G formed by the reinforcing member 8 and bent portions 12 and 12 and the ends 11 and l1 of the members 9 and 9. The portion 16 between the sections 15, and also under the same, forms an anchor for said sections in the road ballast 25 and, thereL fore, helps to maintainthe track in alinement and prevents the ballast from being washed out in case of flood. The shape of the transverse members 13 gives to the lower surface of the sections 15 a convergence toward the portion 1G whereby the strength of the sections 15 greatly increased.

Having thus described my invention, l claim new and desire to secure by Letters Patent:

l; In a reinforcing concrete tie, two distinct load-carrying sections, the center of bearing of each of which substantially in alinenient with the axis of the rail; a web wnnecting and reinforcing said sections and forming an anchor for said 'sections in the road ballast each of said sections having means subsi'. ':.:ia`ily in the center thereof for securing tl l rail thereto.

2. In a rein orcing concrete tie, longitudinal reinforcing members; transveise rein forcing members at each end of said longitudinal members forni' c two distinct load rr),r 'rfi tions, the center of bearing of ch ich substantially in aiinement with the of the rail, said longitudinal members connecting and reinforcing said sections by forming a. web extending under sind i 'tions and constituting an anchor for the tiene in the reatiA ballast, each of sections having a cnslcn substantially in the. center thea-eef and means associated with said cushion whereby a rail can be secured thereto.

in a reinforcing concrete tie, a pair of longitudinal reinforcing members parallel to each other adjacent the top of the tie and having their ends bent to follow the contour of the end and bottom of the with the extremities o said ends toward the top of the tie; a longitudinal member adjacent the bottom of the tie positioned between the bent ends ofthe firstnientioned longitudinal members; transverse reinforcing members positioned at each end of said first-mentioned longitudinal mem; bers between said members and their bent ends, said transverse, reinforcing. members having their extremities bent `over the said firstmentioned longitudinal members and whereby two distinct load-carrying sections are formed, the center of bearing oi' each of which is substantially in alinement with the axis of the rail, said longitudinal members and their bent ends reinforcing said sections and forming an anchor for the same in the road ballast, each of said sections having a concrete,

cushion substantially in the center thereof;

claspsassociated with the cushion and adapted to receive a spike whereby a rail can be secured to the tie, substantially as and for the purpose set forth.

4. In a reinforcing concrete tie, twoA dis tinct load carrying sections `the center of bearing of each of which substantially in alinement with the axis -of the rail; a centrai hingitudinal web connecting said sections and extending thereunder, forming an anchor for said sections in the road ballast; and means in said rail thereto.

5. 'In a reinforcing concrete tie, two distinct load carrying sections having iongitudinal and transverse reinforcing means; a central longitudinal web connecting said sections and extending thereunder and having longitudinal reinforcements therein forming an extension of the reinforcement of the two distinct load carryin'g sections, said web forming an anchor for said sections in the ballast of the road, said sections having means for securing a rail thereto.

6. in a reinforcing concrete tie, two distinct load carrying sections anda web connecting and reinforcing said sections, the cross section of said sections. with web being T-shaped, of which the verticai lnanchv is formed by the web and which web forms'an anchor for said sections in the road ballast. In testimony whereof i have signed my name to this specification in iin-e presence of two subscribnig witnesses.
